D.A.: Conrad Murray lied to investigators

LOS ANGELES, Nov. 3 (UPI) -- A prosecutor in Conrad Murray's involuntary manslaughter trial said Thursday Michael Jackson's doctor lied repeatedly about what happened to the pop star.

Jackson died June 25, 2009, at age 50. Lethal levels of sedatives and the anesthesia propofol were found in his system.

"Unfortunately [Murray's] version doesn't match up with any of the evidence, to the phone records or the text messages or the emails," the Los Angeles Times quoted District Attorney David Walgren as saying in his closing arguments.

Murray, the singer's personal physician, is accused of causing Jackson's death by giving him the drugs to help him sleep, then failing to come to his aid when he was in distress. He also has been criticized for not having emergency equipment on hand or keeping records of his treatment of the recording artist.

Murray has denied any wrongdoing and his legal team suggested during the trial Jackson may have administered the fatal doses of drugs to himself when Murray was briefly out of the room.

Walgren said the circumstances leading up to and immediately following Jackson's death will remain a mystery because Murray has not been truthful.

"How long Michael Jackson was there by himself abandoned, not breathing? We'll never know," the Times said Walgren challenged those gathered in the courtroom Thursday. "Did he gasp, did he choke? Were there sounds? We don't know, and we'll never know."
